Lie Flat

Version: 1.1

Created by: Nomexous

Leírás:
Ez a plugin annyit tesz, hogy mikor eldobod a fegyvert, akkor az "élethűbben", a föld szögével eggyütt fog elhelyezkedni, nem pedig vízszintesen.

Cvarok:
A pluginhoz nincsenek cvarok.

Kép:

Telepítés:
.amxx-t a plugins mappába.
.sma-t a scripting mappába.
Aztán a plugin nevét a plugins.ini -be írd be!
